Function
1: Acquisition vertical sync interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
1: Display Vertical sync interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
1: PWM in timer mode overflow interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
On reset this bit is initialized to 0,however if timer mode is selected
and timer is running, every over flow of timer will set this bit. Therefore
software must clear this bit before enabling the corresponding
interrupt.
1: Acquisition horizontal sync interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
1: Display horizontal sync interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
Central Interrupt Service 1
1: Channel change interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
1: ADC wake up interrupt source bit set by hardware.
Source bit must be reset by software after servicing the interrupt.
0: Interrupt has not occurred.
External Extra Interrupt 1 edge flag.
Set by hardware when external interrupt edge detected. Must be
cleared by software.
Port P3.7 must be in input mode to use this interrupt.
External Extra Interrupt 0 edge flag.
Set by hardware when external interrupt edge detected. Must be
cleared by software.
Port P3.1 must be in input mode to use this interrupt.
Sandcastle
Definition of Hysteresis (slave mode/sandcastle input)
Defines the voltage range for the Hysteresis:
0: Hysteresis set to 0.325 V.
1: Hysteresis set to 0.150 V.
